T-Splines: A Technology for Marine Design with Minimal Control Points

T-splines are a very interesting class of surfaces that eliminate some of the shortcomings of NURBS, and they have been implemented in a Rhino plug-in. They look to be very useful for modeling hulls with local features such as skegs, bulbs, and fading chines, and also extremely useful for more complex surfaces such as sculpted superstructures. The next release of Orca3D will fully support T-spline surfaces; real-time sections, hydrostatics, weight & cost properties, etc. all work with a T-spline surface just as they do with a Rhino NURBS surface. You can read more about this interesting technology at http://www.tsplines.com/. Also, a paper was presented at the recent Chesapeake Powerboat Symposium by Matt Sederberg on T-splines, and there is a link to download it on our website.
